Researchers create new type of composite material for shielding against neutron and gamma radiation
Recently, Dr. Huo Zhipeng and his student Lu Yidong from Hefei Institutes of Physical Science of Chinese Academy of Sciences have created a new type of composite material for shielding against neutron and gamma radiation. They used micron plate Sm2O3.....»»
Researchers develop framework for databasing properties of crystal defects
Point defects (e.g. missing, extra or swapped atoms) in crystalline materials often determine the actual electronic and optical response of a given material. For example, controlled substitutions in semiconductors like silicon are the backbone of mod.....»»
Sustainable, high-performance paper coating material could reduce microplastic pollution
Plastic pollution presents a global challenge that must be solved. In particular, packaging accounts for 30–50% of the total plastic consumption. While paper packaging is eco-friendly, it lacks crucial functionalities like moisture resistance and s.....»»
Study indicates interstitial Cu reduces the defect density in matrix and suppresses the donor-like effect
Due to the capacity to directly and reversibly convert heat into electricity, thermoelectric (TE) material has potential applications in solid-state heat pumping and exhaust heat recuperation, thus attracting worldwide attention. Bi2Te3 stands out fo.....»»
New polystyrene recycling process could be world"s first to be both economical and energy-efficient
Engineers have modeled a new way to recycle polystyrene that could become the first viable way of making the material reusable. The chemical method identified to tackle hard-to-recycle packaging material, cutting landfill waste.....»»
New insights into the degradation dynamics of organic material in the seafloor
The long-term deposition of organic material in sediments on the ocean floor is a key process in the global carbon cycle. The question of whether, from a chemical perspective, the deposited material is more similar to marine algae or the microorganis.....»»
Simulations of swimming fish suggest fish may naturally prefer to compete—not cooperate—during swimming
Researchers have shown how different swimming formations may save fish energy and suggest that they only switch positions to save energy for the group when under pressure......»»
A metal-free organic framework for electrocatalytic production of ethylene from carbon dioxide
Use of the greenhouse gas CO2 as a chemical raw material would not only reduce emissions, but also the consumption of fossil feedstocks. A novel metal-free organic framework could make it possible to electrocatalytically produce ethylene, a primary c.....»»
Using wobbling stellar material, astronomers measure the spin of a supermassive black hole for the first time
Astronomers at MIT, NASA, and elsewhere have a new way to measure how fast a black hole spins, by using the wobbly aftermath from its stellar feasting......»»
We get more useful energy out of renewables than fossil fuels
It costs less energy to get fossil fuels, but we can't use them as efficiently. Enlarge (credit: Yaorusheng) It doesn't take a lot of energy to dig up coal or pump oil from the ground. In contrast, most renewable source.....»»
Can coal mines be tapped for rare earth elements?
Deposits of designated critical minerals needed to transition the world's energy systems away from fossil fuels may, ironically enough, be co-located with coal deposits that have been mined to produce the fossil fuel most implicated in climate change.....»»
The challenges of GenAI in fintech
Due to the cybersecurity disclosure rules the Securities and Exchange Commission (SEC) has adopted in 2023, public entities in the US are required to disclose any material cybersecurity incidents. Moving forward, these organizations will need in-dept.....»»
BLM ends future coal mining on Powder River Basin federal lands
The move compounds pressure on coal communities to diversify their economies. Enlarge / A 133-car coal train moves slowly as it's loaded at the Buckskin Coal Mine in 2006 in Gillette, Wyoming. (credit: Robert Nickelsberg/Getty.....»»
New method may facilitate the use of graphene nanoribbons in nanoelectronics
An international collaborative study that features researchers from Tel Aviv University (TAU), presented a new method for growing ultra-long and ultra-narrow strips of graphene (a derivative of graphite), which exhibit semiconducting properties that.....»»
